 \subsection{Checklist}
 The following things are typically important to know very well (not exhaustive)
 \begin{todolist}
-    \item SQL
+    \item SQL (syntax, some concepts, such as using \texttt{WITH} statements often to make the task more approachable)
     \item Functional Dependencies (including Candidate Keys, Super Keys, Closures and minimal covers)
     \item Normal Forms (and their Decomposition / Synthesis Algorithms)
     \item Time complexities, I/Os and sorted runs for Query Processing
